Robotic snake moves by pushing off obstacles

We'll be honest -- we've seen more snake-like robots than we care to count, but a new creature slithering out of the Norwegian University of Science and Technology is noticeably different than most. As you can see above, there's a distinct lack of treads, tracks or wheels on Aiko, as it actually pushes off foreign objects it encounters in order to creep forward. Additionally, researchers have created a "virtual double" of the critter in order to help guide the development of the actual robot, though we've yet to hear if it plans on joining Anna Konda in war on fire.
